Method and system for sending messages

ABSTRACT

The present publication discloses a method and system for sending messages in a telecommunications network ( 1, 2, 6, 11, 12 ). In the method, a first text-form message ( 54 ) is sent to a user ( 50, 51 ) of the service, a reply ( 55 ) to the first text-form message is received from the user ( 50, 51 ) of the service to an address defined in the previous message, if the reply is of the correct form and content, the desired service ( 56, 58, 61 ) is sent to the user of the service. According to the invention, the user ( 50, 51 ) of the message service is offered a second service by a message ( 62 ), the information (such as the sending number is text-message traffic) defining the reply address of which differs from that of the first message ( 54 ), and the second offer message ( 62 ) is sent with a sending delay, which depends of the content or type of the first service.

The present invention relates to a method, according to the preamble ofClaim 1, for sending messages.

The invention also relates to a system according to Claim 26.

Methods and systems of this kind are used, for example, in theimplementation of text-message-based ordering or booking services.

The prior art is described in, among others, the applicant=s own patentsFI-117663, FI-118586, and FI-118585, and in EP patent application03792441.

These patents disclose solutions, in which, in connection with servicesrequiring many pairs of queries and replies, the management of thedialogue can be most advantageously resolved using simple text-messagetechnology, which is available to all mobile telephone users.

In these solutions, a so-called DDM matrix is used, in which theintelligence of the service dialogue has been transferred to the servicesystem, in such a way that the service provider always changes the replyaddress (typically a telephone number) according to the stage of thedialogue, so that, even in a discontinuous dialogue of long duration,the service provider knows both who has responded to a question in thedialogue and at which stage in the dialogue.

In these, as such highly developed solutions, it has not been simple toimplement all services.

The invention is intended to eliminate the defects of the state of theart described above and for this purpose create an entirely new type ofmethod and system for the sending, particularly the bulk delivery ofmessages, as well as to preferably provide a service for internationaluse.

The invention is also intended to provide methods and means, with theaid of which it is possible to achieve a simple and clear way ofproviding services in multi-channel communications.

In addition, the invention is intended to create methods and means, bymeans of which a query and service can be sent to a customer throughdifferent communications networks.

In a preferred embodiment of the invention, messages, such as textmessages are used in a dialogue, in which content services are deliveredto the customer. The services are provided typically using the serviceprovider's means of payment, such a bonus points. If the customer andservice provider have a mutual agreement concerning other means ofpayment, these can also be used to bill the customer.

The invention is based on the desired reply address, typically thesender data of each message sent, typically by bulk delivery, is changedto correspond to a predefined dialogue, in which the stage of thedialogue determines unequivocally the sender data, in which case thesending and reception of the messages are implemented in different partsof the telecommunications network and the user is permitted to respondin only one way, so that the service is delivered in response to thebilling of the means of payment used by the service provider.

One preferred embodiment of the invention is based on the reception, atthe sender address defined in the in the previous stage of the dialogue,or an address contained in the message, in the message dialogue, of amessage from the user over a second telecommunications channel (dataconnection, VOIP connection, WAP connection, or internet connection) andon proceeding according to the contents of the message. If necessary,the next text-format message of the session is sent to the user of themessage service, in such a way that the sender address (e.g., the Anumber) is changed to correspond to the session number and a new sessionstage.

According to one preferred embodiment of the invention, the interval intime between the first offer message and the following message dependsof the content, size, or temporal duration of the repetition of theservice delivered.

In one preferred embodiment of the invention, the service is deliveredusing a communications channel differing from the telephone connection.

In one preferred embodiment of the invention, the service is deliveredto some other terminal device of the user.

More specifically, the method according to the invention ischaracterized by what is stated in the characterizing portion of Claim1.

The system according to the invention is characterized, for its part bywhat is stated in the characterizing portion of Claim 26.

Considerable advantages are gained with the aid of the invention.

The solution is operator-independent and will operate in the networks ofall operators. The most typical applications of the invention willoperate in any GSM customer telephone whatever, in any network whatever.The invention offers a cost advantage thanks to the bulk delivery whilereception, however, operates entirely country-independently, i.e.completely in a roaming mode from the network of each operator. Inaddition, the system permits the service provider to provide paidservices to existing customers, without risk.

The adjustment of the interval between messages permits bothoptimization of the technical capacity of the telecommunications networkand the optimization of the delivery and acceptance of the messages.

The service can be delivered flexibly to many different terminaldevices.

In the following, the invention is examined with the aid of examples andwith reference to the accompanying drawings.

FIG. 1 shows schematically a solution according to the prior art.

FIG. 2 shows a block diagram of the solution according to the prior art

FIG. 3 shows schematically the data field in a message according to theinvention.

FIG. 4 shows a block diagram of the solution according to the invention.

FIG. 5 shows schematically the system according to the invention.

In the prior art according to FIG. 1, telephone operators A and B havein their own networks text-message bulk-delivery means 3, by means ofwhich each operator can efficiently send large numbers of text messages.In the solution shown, each operator has a common service number 20,which is arranged by agreement, and circuit technology relating to themessage service, which is not available to operators not party to theagreement. According to the prior art, the service number 20 is anon-roaming short number.

In the system according to FIG. 2, there are typically two parties,which, in exceptional cases, can be the same company.

The service company or association 1 provides a service, which providessubscribers 8 with, for example, a registration service for buyingtickets, changing tyres, etc. The service company or association 1operates in a radio network, the home network 13 of some operator.

In the present application, the term service company or association 1refers to an association or company, which operates in either its own oran extraneous network, producing services for customers either directlyor indirectly. Typically, such a company or association is asub-contractor of an actual telephone operator, nor does a user of theservice necessarily even know of the existence of the service company orassociation 1. In a preferred embodiment of the invention, the servicecompany or association produces either directly or indirectly many kindsof registration and booking services for telephone subscribers.

The system also includes a telephone operator 2, in whose network 14there are means and equipment for the bulk delivery of digital messages(such as SMS messages) containing sender data. Such a practical networkelement is, for example, SMS bulk-delivery logic 3, which can beimplemented using, for example, Content Gateway technology.

With reference to FIGS. 2 and 3, in the first stage the service companyor association 1 uses connection logic 9 and number adaptation 4 to forma large number of messages 40, each of which contains recipient data 30,the actual message content 31, and information 32 on either the send or,in practice, the address to which a reply to the message 40 is desired.In an SMS (short message system) application, the recipient data 30 isthe telephone number of a mobile station while the sender data 32 is thesender data in the sender field of the SMS-message sender field 32converted by a number converter 4.

Within the scope of the invention, the message 40 can be any messagewhatever that can be sent through a digital data network, and whichcomprises recipient data, the actual message, and the desired replyaddress, for example, in the form of sender data. Such messages 40 canbe not only SMS messages, but also, for instance, email messages ormultimedia messages (MMS).

A large number of the aforementioned messages are formed dynamically onthe basis of complex dialogues.

When altering the desired reply address, for example, the sender=snumber, the address (or number) from which the contact to the servicecompany or association 1 has been made can be taken into account. Thus,the messages of subscriber=s 8 in the USA can be routed to their ownnational server while correspondingly the messages of Finnish users ofthe same service are routed to their own national server. From thesenational servers, the reply messages can be transferred over suitabletelecommunications links for further measures by the service company orassociation 1.

The messages created by the service company or association 1 are sent tothe bulk-delivery logic 3, which is located in the network 14 of theoperator 2, from which the bulk delivery 5 of the messages isimplemented. From there, the messages 40 disperse always according tothe recipient data 30 and arrive at the terminal device 7 of thesubscriber 8 through the subscriber's 8 radio network 6 at the time. Thesubscriber 8 replies to the message using the ‘reply’ function, when thereply message is sent to the address that determines the value of thesender or reply-address field 32 of the incoming message. The message 40goes to the service company or association 1 over the radio networks 12,11, and 13. Naturally, if the subscriber 8 is in the area of the homenetwork 13 of the service company or association 1, the message will nottravel over the networks 11 and 12. From the home network 13, themessage is transferred to the message reception of the service companyor association, where it is combined with a suitable dialogue with theaid of combination logic 9 and number conversion.

More concretely, for example in an SMS application, when a message issent to the subscriber 8, the sender number (A number) is altered beforebulk delivery in block 4, for example to +35850001, in the first stageof a predefined session (dialogue). The number space of the sendernumber (A number) is defined by the service provider's own number space,which in the invention is entirely independent of the operator's 2number space. In the next stage of the same session, the A number isguided by the logic 9 of the service company or association 1 to be, forexample +35850002, and so on. The sending A number is defined strictlyfrom a logically progressing dialogue created by the service provider 1,in which the reply to each message sent is expected at a specifictelephone number (digital reply address), which is included in theoutgoing message as the A number.

Thus, the subscriber replies to the SMS message using the replyfunction, in which case in the first stage of the dialogue the replygoes to the number +35850001 and correspondingly in the second stage ofthe dialogue to the number +35850002.

Example of a dialogue:

Message Sender number 1. do you want to download a piece of music? replyy/n +35850001 2. do you want to download the video of the piece you+35850002 heard? reply y/n

The subscriber's 8 reply ‘y’ sends the message 2 of the serviceprovider's 1 system. The dialogue terminates, if the reply to the firstmessage is ‘n’.

Thus the messages described above are sent to several recipients at onetime, in which case the A number (=field 32) of the first stage of thedialogue would always be +35850001 and correspondingly in the secondstage of the dialogue always +35850001, so that the reply to eachmessage sent will always be assigned to the correct number. Inconnection with the reply, the sender's 8 A number defines to whom thebooking will be made.

According to the invention, the preferred embodiment is an SMS message,but, according to the invention, the message can also be some other formof digital short message, in which the message can be replied to,without separately defining the recipient. Thus, instead oftelephone-number data, the sender or reply address field (field 32 inFIG. 3) of the message can contain the desired reply address in someother form, for example, as an email address, or as numerical oralphanumerical sender or reply address data.

Thanks to the number conversion, the reception of the message takesplace typically in an open radio network (or alternatively e.g., in awireless local network, such as a WLAN or similar) external to thenetwork of the operator 2 sending the message and is routed on the basisof the A number to the system of the service company or association 1.

Thus, in the invention in the SMS application, prior to bulk deliverythe data in the ‘sender’ field of the text message being sent isaltered, in such a way that the value entered in it is different to thesender's real number. This value is obtained from the logic 9, 10 of theservice company or association 1, according to a predefined rule, insuch a way that the questions and replies arriving at the logic can belinked.

In addition, in the system of the service company or association 1,there is logic 9 connecting the sending end and the receiving end, whichcan link a sent message and its incoming return reply from the externaloperator 2, in such a way that a subscriber can reply (from outside thenetwork) from any subscription at all, but, however, sending can be donefrom inside the network at a high capacity and economically. In otherwords, the cheapest sending operator can be selected, but reception canbe from any data network whatever.

According to the invention, at the message-receiving end it is possibleto distribute the reception in such a way that, for example, in Swedenreception takes place at a local network element and correspondingly inFinland at a Finnish network element, from which national networkelements the messages received are transferred over suitable links, forexample IP links, to the system of the service company or associationfor further processing. The international roaming of the service willthen be faster and cheaper, as well as more reliable. In addition, it ismore pleasant for a consumer to use the service, because sending takesplace to the number of a local operator and not to the network of aforeign operator, which is perceived to be expensive. In somesubscriptions, foreign text messages may even be blocked, i.e. they willnot operate without the service according to the invention.

According to FIG. 4, the solution according to the invention isimplemented as follows.

A logically continuous, but temporally discontinuous session N of longduration is implemented as follows. The session N is divided intosub-stages J (43, 41, 42), which are typically temporally separated fromeach other. The session N itself is, however, logically continuous, inother words the queries and replies proceed logically over the entiresession.

The service relating to the session N is initiated in block 43. Thefirst text-form message of the session N is then sent to a service user,in such a way that the sender address (e.g., the A number) is altered tocorrespond to the session number N and the session stage J. Block 42depicts the stages 2-n of the session N, in which a text-form message tothe sender address defined in the message in the previous stage isreceived from the user of the message service, and which proceedsaccording to the contents of the message, in such a way that the senderaddress (e.g., A number) is altered to correspond to the session numberN and the new session stage J. Next, the next text-form message ofsession N is sent to the user of the message service.

According to block 42, an additional stage according to the invention isimplemented at some stage of the process, in which the service provideroffers a service subject to payment and, in reply to this offer message,acceptance of the delivery of the service subject to payment is receivedfrom the user of the message service.

According to FIG. 5, the method and system according to the inventioncan be applied in an environment, in which there is a service provider52, for example an airline. In addition to this, there are severalusers, of which the figure shows one user, who has two terminal devices,a mobile telephone 50 and a laptop or palm computer 51. In addition, thefigure shows the service producer 53 and the public internet network 60.Instead of the internet network, it is also possible to use, forinstance, a WLAN network, or a corresponding telecommunications network.

The method according to the invention proceeds in such a way that theservice provider typically approaches the mobile stations 50 of severalusers and sends an offer 54 of a service, for which payment will be madeusing the service provider's own means of payment, such a bonus points(or frequent-flyer miles). The user is given the chance to reply and thedelivery process of the service typically initiates only if anunequivocal acceptance message is received from the user 50, forexample, ‘y’, ‘yes’ or some other corresponding short message, forexample in the form of a text message.

Once the process has been initiated by the unequivocal message, theservice is sent, either directly as a download 56 to the mobiletelephone, or alternatively the message 56 can be a text-message link tosome other telecommunications system, such as the link address of theservice provider 53, from which the actual service such as music or animage is downloaded by means of a return message 58. The connection fromthe mobile station 50 to the system 53 can be based on WAP, WLAN, orsome other suitable technology.

Because the service provider has typically comprehensive information onthe data of its customer, such as the service profile and the availabletechnology, the service can be delivered 59 directly to the seconddevice 51 of the user, or in parallel to both the telephone 50 and thecomputer 51 of the user.

In the solution of FIG. 5, the first offer message 54 is followed by asecond service offer message 62, which is preferably sent after a delayrelative to the first message 54 that corresponds to the combined timeof the delivery and use of the first service to be delivered. Typically,this transmission delay can be the duration of the delivered music orvideo performance, added to the time taken to send the service. Instreaming services, in which the service is delivered as a bit streamafter the acceptance of the service, the delay is correspondingly thetime between the acceptance and the termination of the bit steam. In thepresent application, the term streaming refers to a term generally usedin the field, in which previously ordered material is delivered to theuser or customer as an essentially continuous data stream suitable foruse immediately. The definition thus differs from a file downloadservice, in which the user or customer of a data network downloads afile and uses the service contained in the downloaded file with the aidof their own software, when the need for use arises, without thetransfer services of a data network.

Generally, it can be said that in the present system existing technologyis mainly used to initiate the dialogue of text messages. Filedownloads, on the other hand, are typically implemented by datacommunications, for example, by exploiting a suitable communicationschannel in multi-channel operation. In the example of FIG. 5, the datalinks are typically used in the messages 57, 58, 59, and 61, whereas themessage 54, 55, 56, and 62 are typically text messages.

Particularly when network and terminal-device technology develops, itwill naturally be possible to implement solutions, which may deviatefrom the general principles described above.

In terms of practical implementation, a problem is the estimation of thereal amount of the delay, because both the telecommunications networkand the service user too can be loaded and the time greater than theoptimal time permitted by the telecommunications network.

Thus, according to one embodiment of the invention, the transmissiondelay between the first 54 and the second 62 offer messages is definedon the basis of the contents or type of the service.

According to one preferred embodiment of the invention, the transmissiondelay is typically defined as the sum of the typical reproduction timeand the typical transfer time.

According to a second preferred embodiment of the invention, thetransmission delay is defined as a function of the file size.

According to a third preferred embodiment of the invention, thetransmission delay is defined according to the file type.

In the following is an example of one dialogue:

Message Sender number 1. Do you want to use your bonus points todownload +35850001 music at a price of 500 p/piece? y/n 2. Reply ‘y’ tonumber +35850001 3. Delivery of service 4. New message at a delayproportional to the content +35850005 to the same customer number ‘Doyou want to download a new piece or video?’ 5. Reply ‘y’ to number+35850005

According to the invention, a service can be implemented as a groupmessage at an airport as a group message to those going to one aircraftand, after this, the service dialogue can be tailored in the aircraft inthe area of coverage of the aircraft's base station, on the basis of thereplies and choices of the individual users.

A single user can naturally have more than two terminal devices.

The services can be music, image, or video content, or search services,dictionary services, or similar. Within the scope of the invention,providing a service against payment can also comprise the user agreeingto receive advertising material in lieu of payment for the service.

In the present application, the term sender data refers both to atelephone number (A number) and to any information whatever of thedesired return address transported with the message.

The method and system according to the invention are implemented withthe aid of at least one computer in telecommunications networks.

According to the invention, the sender address can also be an IPaddress.

Some preferred embodiments of the invention are described in thefollowing.

PREFERRED EMBODIMENTS OF THE INVENTION

In principle, all preferred embodiments described in the following areassociated with the query and reply addresses (numbers/IP addresses,etc.) being able to be combined with a specific question. The timing ofthe transmission of a new question can be made in several differentways. Alternative ways include timing relative to the time taken totransfer the file and the time taken to download, in which case thetiming delay can be directly the sum of these times or proportional tothem. It is also possible to use a transmission delay, which is the sumof the transfer time and the reproduction time added to a constantamount of additional time. The additional time will be necessary, if,for example, the transfer speed of the data network is not stable.Alternatively, the timing delay can always be of a constant magnitudeaccording to the message type. The queries can be also be sent nearlysimultaneously, or alternatively a sign (bit, flag, etc.) can beattached to the file to sent, and sent back to the service provider onethe download/listening/viewing has taken place. The last alternative mayrequire a short program to be installed in the terminal device, so thatthe notification in question can be send to the service provider.

The embodiments are described with reference to FIG. 5.

In one embodiment of the invention, the offer message 54 is sent (as atext message) from the service provider to the customer (do you want acertain piece or video). Transmission can take place, for example, overa GSM network.

Customer replies 55 y/n.

The piece or video is sent 56, 58, 61 to the terminal device 50, 51(cellphone or otherwise defined terminal device, e.g., laptop computer)of the customer. The piece or video is delivered, e.g., over a dataconnection.

After a specific time, a second message 56 is sent to the customer (witha different reply address to the first message), in which the customeris asked if they want a new piece or video (piece or video offered canbe selected, e.g., on the based of previous selections by the user, onthe basis of the user's profile, etc.).

The customer replies y/n.

If the customer replies y, the aforementioned series of stages can startfrom the beginning in the case of a new piece or other service.

According to another embodiment of the invention, an offer message issent (as a text message) 54 from the service provider 52 to the customer(do you want a specific piece or video). The service can be implemented,for example, through a GSM network.

The customer replies y/n.

The customer is sent a text message 56, in which an individuated IPaddress 57 is given, from where they can fetch the piece or video.

After a specific time, a new query message 62 is sent with a differentreply number.

The aforementioned process is repeated concerning the delivery of newqueries and products.

According to another embodiment of the invention, a query message 54 issent, for example over a local network in an aircraft, to customers whoare within the coverage of the network (the message can be sent eitherto a cellphone or a computer, etc.).

The customer replies 55 y/n.

A file is sent to the customer 56, 58, 61.

A new query 62 is sent to the customer. In this query, there is adifferent reply address to that in the previous sent message.

The process is continued in the manner described above in the case ofthe second service (piece of music, or similar).

In all of the above cases, the timing of the transmission of the nextmessage can be predefined. For example, a new message 62 is sent attwo-hourly intervals, or the message is sent immediately after thereception of the previous reply. The situation can also be such that,after the reception of the first reply, new messages are sent to thecustomer at short intervals. In that case, in all of these messagesthere should be different reply addresses, so that it is possible toidentify the question to which the customer is replying.

In addition, the cases described above can also be performed using othermessages than text messages.

If the piece of music or video is delivered directly to the customer'stelephone, the service provider must known whether the customer'stelephone supports transmission and performance formats of the kindused. This can be determined from the service provider's customerprofile, provided these data are maintained sufficiently actively. Theservice provider's customer profile can also contain information onwhether the customer has in use several different types of terminaldevice, such as palm computers, laptop computers, or smart telephones.

If the aforementioned services are offered in a single aircraft orotherwise restricted area, this system should also include a possibilityfor several numbers/addresses to be used as reply addresses. In thatcase, it is possible, for example, to implement a number pool in theaircraft's server, which will then act as the service supplier.

In another embodiment of the invention, if the service provider is, forexample, an airline, which has its ‘own’ subscription and sufficientlycomprehensive information on the customer and connections to, forexample, travel agents and/or hotels and/or taxi firms, etc., thefollowing kind of embodiment can also be taken into account.

A customer books a flight from Helsinki to Berlin. If the customerchecks in using their cellphone, the service provider can send themvarious kinds of message. The messages can contain, for example,ordering a taxi to be ready at the airport when the flight lands inBerlin, booking a hotel, and many other possible functions. When thecustomer lands in Berlin, switches on their cellphone and the cellphoneregisters on a network, offers can be made to them concerning, forinstance, music, videos, ordering a taxi, hotel booking, etc.

At a principle level, the process then proceeds as follows:

The customer receives a message(s) from the service provider of theairline (either the airline itself or a service provider acting as itsagent), by replying to which they can check in using their owncellphone. The service provider then knows the destination and time oftravel of the customer.

When the customer lands at their destination and switches on theircellphone (when connection to a network takes place), the serviceprovider sends a text message 54, in which it offers services to thecustomer (taxi, piece of music, video, hotel, map service, etc.).

The customer replies whether they wish to receive the service.

If the customer replies yes, the service is delivered to the customer.

The service provider 52 sends the following query from a different replynumber to the first query, so that the system knows the question towhich the reply is made, who has replied, etc.

The invention is not restricted to the embodiments described above,which are only example, of the invention described in the Claims. Thus,one skilled in the art will be able to made several alternativesolutions, without leaving the scope of protection described in theClaims.

Thus, for example, the message can be, according to the invention, alsoa multimedia message (MMS) instead of an SMS message. The message typecan vary within the invention, in other words it can start as amultimedia message and use at least one text message as a furthermessage, or vice versa.
